,XLLE FOR lWOTOlXf VEHICLES.

`State of Michigan, have invented lcertain new and useful improvements in Axles ior Motor f'lehicles, of' which thev tolloiving` is a specification, referencel being had` to the accompanying drawings.A

My invention relates to axles, and has to do particularly with' rear, arles for; motor vehicles such as trucks inwhich the rear Wheels are driven y'from the i rear axle and 'are provided with brake drums adapted to cooperate with brakes supported by and con neet-ed With the axle. ln vehiclesoi this description the reark axle is usually enclosed in a housing, which also eneloses the differential gearing through which the rear axle is driven from the motor,` and the brakes are supported by brackets secured to the :outer end portions of the housing, and the object of my invention is to provide certain improvements in axles ot this description by Which the brake ksupporting brackets maybe better. secured to the yhousing so that they Will be capable ot .vith-` standing the strains -to Which they are subjected Without dangerfot becoming disconnected or loosened. l accomplish this object as illustrated in the drawings and hereinafter described. What l regard as neu7 is set forth in the claims.`A

In the draWings,- f f .y

Fig. 1 is a partial plan view :of a Wheel and axle embodying my invention, some parts being in section;y

Fig. 2 is a partial sectional view on line 2 2 of Fig. 1;

Fig. 3 is a partial longitudinal sectional view oft the central portion oi'one ot the brake supporting brackets; and` Fig. i is a partial. perspective view of the outer end portion of the axle housing.

`As both end portions oil", the axle are alike, 'l have illustrated. and described only one end portion thereof. ln the drawings, 5 indicates the axle, the inner -end portion of which is connected with the usual dierential gearing, and the outer end portion of which is connected with one of the vehicle Wheels 6 in such manner that rotation oi the axle causes the Wheel to rotate. yits shown in Fig. 1, the Wheel is provided with the usual brake drum 7 at its inner side,

and this may be mounted in any suitable' Wayhon the wheel. rlhe axlek 5 extends through a tubular housing 8, the central portion of which is connected with the" usual differential"housing,and tle outer end portion/ol: said housing is provided with an. internal sleeve 9 which is iixedly secured thereto, preferably by rivets passing through rivet holes 10 shown inrliig. e. As best shown in l the intermediate portion ofthe housing is tapered, but the sleeve 9 `is preferably ol funi'i'orni diameter throughout, its inner end portion being supported and braced by a collar 11 which is litted tightly between 'it and 'the tapererL inner face or the housing 8 as shown in Fig. 1. The outer end of the sleeve 9 is flush With the outer end of the housing 8, as shovvninFigs. land e, 'and these ends are cut back to Ytorni tenons 12'Which project from the outer ends ot'the said meni- 'bers as shown in l forming a clutch member, the purpose oi Whichlwill be' hereinater pointed out.

Mounted upony the outer end portion of the housing 8 is a brake supporting bracket 13 Which comprises a hub portion 1li and oppositely extending arms 15, 16 on which the brakes are carried; rlhe hub portion 14e is mounted on an anti-friction bearing 1T carried bythe axle 5 as shown in Fig. 1, and is provided with a laterallyy extending sleeve 18 which telescopes upon the outer endportion of the housing S, and isirinly secured thereto bythe rivets which connect the housing 8 With the sleeve 9., These rivets serve `to prevent .movement of the' sleeve 18 on the housing 8,*but they' are intended principally to hold `said sleeve against endvvise movement, asy the torque strains are principally taken care of by other means provided for that purpose, and the use of .rivets alone does not provide a sufficient margin oi safety to eliminate danger of breakage. .As best. shovvn in liig. 3, they sleeve 18 :is provided With inwardly projecting segmental lugs 19, which forni a clutch member adapted to interlock with the clutch member formed at the outer ends of the housing Sand the sleeve 9 by the tenons 12, so that When the sleeve 18 is fitted upon the housing 8 in the manner shown in Fig. 1, the tenons 12 yand lugs 19 interlock with each otherl and therebyv prevent rotation of the sleeve 18 upon said housing 8. By

CIK

this means the rivets above referred to are entirely relieved of the torque or braking strains, and need be strong enough only to prevent longitudinal movement of the sleeve i8 on the housing. The sleeve 9 reinforces the housing 8 at the points Where strength is necessary, and makes it practicable to make the housing proper of lighter material. The internal brake is shown at 2O in Fig. 2, and the brake-operating shaft at 21 in Figs. l and 2. This shaft is supported by the arm l5 of the brake supporting bracket, the brake itself being supported by the arm 16 of said bracket in the usual Way. rlhe spring seats, the lower inembers 2:2 of which are shown in Fig. l, are mounted upon the sleeve 18 as shown in said ligure.

What l claim as my invention and desire to secure by Letters Patent, is-

l. rlhe combination with an axle, of a housing through which said axle extends, and a brakesupporting bracket having interlocking engagement with said housing arranged to prevent relative rotation thereof.

2. The combination with an axle, of a housing through which said axle extends, a brake-supporting bracket having interlocking engagement with said housing'arranged to prevent relative rotation thereof,

and means for preventing relative endivis'e' movement of said members.

3. The combination with an axle, or va housing through which said axle extends, and a brake-supporting bracket mounted `upon said axle and having'interlockino engagement with said housing arranged to prevent relative rotation thereof.

4, The combination with an axle, of a housing through Which said axle extends, a brake-supporting bracket, an anti-friction bearing between said bracket and said axle, and interlocking means for nonrotatably securing said bracket to said housing.

5. The combination With an axle, of a housing through which said axle extends, a`

brake-supporting bracket telescopically engaging said housing, andy interlocking means non-rotatably connecting said brack-v et with said housing.

6. The combination with an axle, of a housing through WhiChsai'd axle extends, a brake-supporting bracket telescopically engaging said housing, interlocking means non-rotatably connecting said bracket with said housing, and means for preventing relative endwise movement of said bracket and said housing.

7. The combination with an axle, of a housing through Which said axle extends, a brake-supporting bracket mounted on said axle, and lugs carried by said bracket and engaging the outer end portion of said housing for non-rotatably securing said members together.

8. The combination with an axle, of a housing through Which said axle extends, a brake-supporting bracket mounted on said axle, and lugs carried by said bracket and engaging the outer end portion of said housing for non-rotatably securing said members together, said bracket having a sleeve telescopically fitted upon said hous- -ing and riveted thereto.

9. The combination with an axle, of a housing through which said axle extends, a sleeve fitted inthe outer end portion of said housing and secured thereto, and a brakesupporting bracketfhaving interlocking engagementvvith said housing and-sleeve arranged to prevent relative rotation thereof. v

l0. The combination with an axle, of a housing through which said axle extends, a sleevev fitted in the outer end port-ion of said housing and secured thereto, and a brake-supporting bracket having interlocking engagement With said housing and sleeve arranged to prevent relative rot-ation thereof, said bracket having a sleeve telescopically fitted uponA said housing and secured thereto.
